Fabrication and Mechanical Characterization of Bagasse, Rice Husk, Saw Dust Reinforced Epoxy Composites

摘要

Paddy and sugarcane are commonly harvested around the world along with Bangladesh. The abundant amount of byproduct of these crops can be efficiently used industrially to produce reinforced composites product. In this paper, the effects of the weight percentage of sugarcane bagasse on compressive and tensile properties were evaluated, in conjugation with rice husk and sawdust. The composites were fabricated with 40 wt. % of epoxy resin as a binder with other filler by press forming and the wt. % of binder was kept constant. The lower percentage of binder made the composites cost effective with another advantage of lightweight, biodegradability and eco-friendly. The wt. % of sawdust was kept the same for each specimen to evaluate the consequence of wt. % of bagasse. Among the filler component, the percentage of bagasse was varied to 10 wt. %, 30 wt. %, 50 wt. % and 70 wt. %. In this study, it was evaluated that with the decreasing of the wt. % bagasse the tensile strength increased. The compressive strength increased up to certain decreasing weight percentage of bagasse and after that again the compressive strength decreased.
